Hello all,
We're having difficulities adding an on-prem SSAS analysis service connection through a blank query on a Dataflow. I've added the correct Power Query:
let
Source = AnalysisServices.Database("xxxx", "xxxxx", [TypedMeasureColumns=true, Implementation="2.0"]),
xxxxx1 = Source{[Id="xxxxx"]}[Data],
xxxxx2 = Invoice1{[Id="xxxxx"]}[Data],
#"Added Items" = Cube.Transform(xxxxx2,
{
{Cube.AddAndExpandDimensionColumn, "[BUL]", {"[BUL].[BUL].[BUL]", "[Business Unit Line].[BUL Name].[BUL Name]"}, {"BUL.BUL", "BUL.BUL Name"}}
})
in
#"Added Items"
After we do that we get the following error after using the correct credentials:
Received error payload from gateway service with ID xxxxxxx: Internal error: MashupCredential for AS data source that uses Windows authentication needs to have an effective user name authentication property.
I appreciate any help on this. I will add that we already voted to add SSAS on-prem as a datasource direct in Dataflows, so we don't need to use blank queries, but we need something in the mean time. Thanks.
Hi @SELECTDBA ,
Based on this document,
The following list shows which connectors you can currently use by copying and pasting the M query into a blank query:
It seems the On-Premises SSAS does not supported to used with Blank query in Dataflow.
We also tried to connect with a AS query in Dataflow with a gateway, but we get a InvalidDatasourceTypeForSkipTestConnectionError
Best regards,
@v-lid-msft thanks for the response and the link. I can't help but think how big of a mistake this is on Microsoft's part - I wouldn't assume they would have an oversight this big, so maybe there is a reason? Anyway, what do you think about a OLE DB connection to SSAS? I tried that, but I was getting a different error. I wasn't sure if anyone had success there. Thanks.
Thanks for the response, @GilbertQ. I did get and try that query in Power BI Desktop, and it worked fine there (the account is an admin on the SSAS box). Is this something you have ever got to work? Thanks again.
Do you have any docs for this? we are getting the same error.
